Arun was to find 6/7 of a fraction. Instead of multiplying, he divided the fraction by 6/7 and the result obtained was 13/70 greater than original value. Find the fraction .
A7/8
B3/5
C3/7
D5/7
Answer:
B. 3/5
Read Explanation:
Let the fraction be x
Original value to find = 6x/7
(6x/7) = 7x/6-13/70
7x/6 - 6x/7 = 13/70
(49x - 36x)/42 = 13/70
13x/42 = 13/70
x = 42/70
x = 3/5
